2.2 CSI-2 Aggregator without Using SerDes

This type of aggregator can directly interface with multiple MIPI CSI-2 cameras and aggregate the data from all cameras to a single CSI-2 output stream.

Figure 2-3 shows an example of such a system. This type of aggregating design does not use any serializer or deserializer, but is limited by the maximum distance of CSI-2 data transfer, which is up to 30cm. The AM6x Linux SDK does not support this type of CSI-2 aggregator.
